Question 12
A student performing a biological specimen studies using cancer cells, wants to check
the changes in pH of the cells. The cancer cells are known to be acidic compared to
normal cells (not going into details), the normal cells are expected to be in range of 7.2
to 7.5, while cancer cells in the range of 6.4 and 7.0. Can the student use the Methyl
Orange dye that was synthesized in the lab for this analysis?
O YES
O NO
O Methyl Orange is not a pH sensitive dye
O No answer text provided,
During Friedel-Crafts Acylation, the first compound eluted from the column is the
product
O True
O False
Question 10
Propose a simple and easy technique other than Column chromatography that can be
used to understand the reaction progress during FC acylation
Melting point
O Recrystallization
O TLC
O None of them will provide required information

During oxidation experiment, you are asked used to add one or two drops of aqueous
sodium bisulfite into the reaction
O for killing excess of Acetic acid
O to neutralize excess of hypochlorite ion
O to protonate the Bleach
